【摘要】：三峽庫(kù)區(qū)蓄水后水文變化從以前的自然水文變成了庫(kù)區(qū)水文條件,而且隨著水文條件的改善,三峽大壩上游的通航能力也得到極大的提高。但伴隨著的也是碼頭的使用頻率增加、負(fù)荷增高使碼頭不斷的破損。因此碼頭檢測(cè)的重要性不斷增加,而目前碼頭檢測(cè)評(píng)估還稍落后于其他行業(yè)。本文主要以三峽庫(kù)區(qū)成庫(kù)后帶來(lái)的各種改變對(duì)高樁碼頭帶來(lái)的影響為依據(jù)。并根據(jù)高樁碼頭所處環(huán)境,以及結(jié)構(gòu)特點(diǎn)�？偨Y(jié)三峽庫(kù)區(qū)碼頭病害,建立檢測(cè)技術(shù)指標(biāo)體系。并從橋梁檢測(cè)中引入并適當(dāng)修改了檢測(cè)技術(shù)標(biāo)準(zhǔn),使碼頭檢測(cè)技術(shù)標(biāo)準(zhǔn)更詳實(shí)。本文研究以結(jié)構(gòu)可靠度為基礎(chǔ)理論,運(yùn)用AHP層次分析中的專家調(diào)查法,對(duì)碼頭檢測(cè)、碼頭結(jié)構(gòu)設(shè)計(jì),碼頭安全方面的教授進(jìn)行調(diào)查問(wèn)卷研究獲得權(quán)重系數(shù),然后借鑒并改動(dòng)部分橋梁中的評(píng)分公式,使碼頭評(píng)價(jià)能有一個(gè)較為量化的數(shù)字指標(biāo),而不是以前的一個(gè)完全是定性的檢測(cè)結(jié)論。然后在定量的基礎(chǔ)上運(yùn)用了模糊評(píng)價(jià)中F法的半梯度法將定量的分?jǐn)?shù)轉(zhuǎn)為對(duì)碼頭健康的一個(gè)定性等級(jí)描述,研究三峽庫(kù)區(qū)高樁碼頭的健康檢測(cè)評(píng)價(jià)體系。最終形成一套操作性強(qiáng)、易理解的檢測(cè)體系。因此這樣的評(píng)價(jià)結(jié)果可以讓人對(duì)碼頭健康同時(shí)有定性的和定量的結(jié)果,更加易于理解碼頭整體健康等級(jí),以及更易于了解碼頭的整體健康狀況。對(duì)三峽庫(kù)區(qū)高樁碼頭檢測(cè)評(píng)估的發(fā)展有著較大的幫助。
[Abstract]:The hydrological change of the three Gorges Reservoir has changed from the former natural hydrology to the reservoir hydrological condition, and with the improvement of the hydrological condition, the navigation capacity of the upstream of the three Gorges Dam has been greatly improved. But also accompanied by the increase in the frequency of wharf use, the increasing load of the wharf is constantly damaged. Therefore, the importance of wharf inspection is increasing, and the evaluation of wharf inspection is lagging behind other industries. This paper is mainly based on the influence of all kinds of changes brought by the three Gorges Reservoir area on the high pile wharf. And according to the environment of the high pile wharf, and the structural characteristics. This paper summarizes the wharf diseases in the three Gorges Reservoir area, and establishes a technical index system for detection. The technical standard of bridge detection is introduced and modified appropriately, which makes the technical standard of wharf detection more detailed. In this paper, based on the theory of structural reliability, using the expert investigation method in AHP hierarchy analysis, the weight coefficient is obtained by questionnaire research on wharf detection, wharf structure design and wharf safety. Then the scoring formula of some bridges is used for reference and modified so that the evaluation of wharf can have a more quantitative numerical index instead of the former one which is completely qualitative. On the basis of quantitative analysis, the semi-gradient method of F method in fuzzy evaluation is used to change the quantitative score into a qualitative description of wharf health, and the health detection and evaluation system of high pile wharf in the three Gorges reservoir area is studied. Finally, a set of operational, easy to understand detection system is formed. Therefore, the evaluation results can make people have both qualitative and quantitative results on the wharf health, make it easier to understand the overall health grade of the wharf and understand the overall health status of the wharf. It is of great help to the development of the inspection and evaluation of the high pile wharf in the three Gorges Reservoir area.
